Regarding 'surgical dislocation of the hip versus arthroscopic treatment of femoroacetabular impingement: A prospective matched-pair study with average 2-year follow-up'

摘要

We read with interest the article entitled "Surgical Dislocation of the Hip Versus Arthroscopic Treatment of Femoroacetabular Impingement: A Prospective Matched-Pair Study With Average 2-Year Follow-up." This is a very interesting topic that has evolved significantly in recent years, and we appreciate the question posed by the authors. There are several points of interest that deserve mention. First, despite the fact that all patients were reportedly offered either surgical hip dislocation (SHD) or arthroscopy, in the end, 10 SHDs were included without a noted denominator, and only 20 of 684 of the arthroscopic cases were included in the final cohort and analysis. Although the authors attempted to match the groups, it would be more valid to include a large proportion of both groups rather than a large proportion of one small group and a very small proportion of another very large group. It is not clear that the 20 of 684 hip arthroscopies are representative of the entire arthroscopic cohort. Second, there is a significant, yet poorly defined, learning curve for both open and arthroscopic hip preservation procedures, and it is possible that the authors were more proficient at arthroscopic FAI correction compared with SHD, as suggested by the numbers presented.
